Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33609878, here are decompositions:

61 + 33609817 = 33609878
109 + 33609769 = 33609878
157 + 33609721 = 33609878
229 + 33609649 = 33609878
271 + 33609607 = 33609878
307 + 33609571 = 33609878
331 + 33609547 = 33609878
349 + 33609529 = 33609878

Showing the first eight; more decompositions exist.
